Cons: I've had 2 sets of Uniden phones over the past 4 years or so, the first one the menu button started to be unresponsive then totally stopped working. This second set was given to us, and somewhere between 6 months to a year, same thing. I'm not buying Uniden anymore after experiencing the same problem on 2 completely different models.
Summary: WHEN I BOUGHT THE ORIGINAL SET WITH BASE AND 3 PORTABLES, I DIDN'T REALIZE THAT THE BASE COULD HANDLE 6 PORTABLES.GREAT CLARITY OF SOUND.[...]. THE NEW INSTRUMENTS WERE EASY TO INSTALL.I'M A VERY HAPPY CAMPER!
Summary: everything about the base unit has been perfect. The phone has a long battery life out of the cradle. I purchased this extra unit, and it set up easily with the base unit. The only thing it doesn't do is add your phone book, you have to place them all in the unit over again.
